Do you still use 32 oz. dry measure per gallon as you would with prismatic rice crystals?
OK, as you may have seen from my post earlier today, the amidol and fix have arrived. A couple of questions about mixing now...
I bought 4 1 liter units of the Michael A Smith formula. The kits each have 30 g of Sodium Sulfite, 3 Grams Citric Acid, & 8 Grams of Amidol. Also included was a seprate baggie of Pot. Bromide 10 grams.
Looking at Michael's site, the Amidol formula calls for KBr (10% solution) 2 cc . IU imagine that this is the Pot. Bromide. How do I make this solution? and is 10 Grams enough for 4 liters of Amidol? I Plan on making it just prior to use each printing session.
Dunno - I've bought "chem lab authorised" Nalgene bottles in all sized from 100cc to 2liter, just to have enough. I figure you can never have too many bottles - just like trays - and find the 100cc ones really useful for all those fiddly little solutions. Like Pyrocat-HD, or Silver Nitrate for salt prints.
And mixing the 10g with 100cc water is what you're after, yes.
I bought small brown glass bottles...Maybe 20 oz? from one of the photo materials suppliers (believe that it was B&H). I imagine that any of the dealers that you have there should have them. If you can't locate them there, you might check a lab supply house. Good luck with the Amidol and Azo...I imagine that you will be in for a pleasant surprise. I know that I was.
